What is the main function of the cell membrane of a cell?
A. to exchange nutrients and the cells waste with the external environment
B. to limit the size that cell can reach
C. To organize the cell's internal contents
D. to protect the cell from harmful substances in the environment
Answer:
D. to protect the cell from harmful substances in the environment
Explanation:
Cell membrane is also known as plasma membrane is a biological membrane that differentiate the internal organelles of the cells from the outside environment. Cell membrane is made up of phospholipid bilayer with embedded proteins.
The main or primary function of cell membrane is to protect cell from harmful substances in the environment as it is the outer convering of the cell. cell membrane regulates movement of substances in and out of cells which restricts entry of harmful substances and hence called as selectively permeable membrane.
Hence, the correct option is D.

Provide a summary of biologist Stephen Stearns’ findings in how Natural Selection may be working today in humans.
Answer:
Stephen Stearns states that natural selection doesn't mean the survival of the fittest organisms, but rather this mechanism is illustrated by the selective reproduction of the fittest. Natural selection can be classified into distinct types, including directional, disruptive and stabilizing selection, which are in turn based on sexual selection. These types of selection are driven by different outcomes that have different dynamics.
do capillaries transport blood from arteries to veins?

The high temperature on Friday was 8 degrees above zero. The low temperature was 3 degrees below zero. Which expression gives the average of the low and high temperatures?
a
Left-bracket negative 3 + (negative 8) right-bracket divided by (2) Right-bracket
b
(negative 3 + 8) divided by 2
c
(negative 3 + 8) divided by (negative 2)
d
Negative (3 + 8) divided by 2
Answer:
B
Explanation:
The negative goes by the 3 because it is 3 degrees below zero. To find averages, you add the numbers and divide by how many numbers there are. in this case, it would be (-3+8)/2

Answer:
"The cricket population would increase"
Explanation:
Without mice as a natural predator, there would be no regulation as to how many crickets live in an area, thus there would be an excessive amount of breeding which can lead to mutations and more sick crickets than healthy ones. The mice pick off the sick/ slower ones so the naturally stronger crickets can pass on their genes to future generations.
Answer:
The cricket population would increase.
Explanation:
If there were no more mice to eat the crickets, the crickets would have a larger population.

The pH of a solution determines the charge of certain R groups. The pH of pineapple fruit ranges from 3.5 to 5.2. Predict the effect on the activity of bromelain if it is used in a product with a pH of 11.
Answer:
The activity of Bromine will reduce
Explanation:
Bromine is found in pineapple stem with pH range of 3.5- 5.2 this implies that the environment where bromine is found is acidic hence when taken to a product whose pH is 11 which is basic then its performance will be low because its can only function well in an acidic medium.
pH ranges tell whether a substance is acidic, basic or neural.
Acid range from 3.5-6
7- neutral
8 above is basic
This is about knowing the behaviour of some elements in different PH Values.
The activity of bromelain will decrease in a product with a pH of 11. .
We are told that the PH of pineapple fruit is of the range of 3.5 - 5.2. In reality, this also includes it's stems and the plants as well. This falls into the acidic range because PH less than 7 is acidic.Now, these stems, plants and fruits of pineapple usually contain bromelain. This implies that bromelain does its' work in an acidic environment since pineapple has an acidic PH.If bromelain is used in a product with a PH of 11, it means it is being used in a basic environment because a PH greater than 7 indicates a basic nature. This means bromelain will not function as well as it did in the acidic environment and as such the activity of bromelain here would decrease.We can now conclude that the activity of bromelain will decrease in a product that has a PH of 11.

Which explanation below is the most accurate regarding animal and plant adaptations for survival in a desert biome
Answer:
i think its C sorry if I'm wrong
Explanation:
The most accurate regarding animal and plant adaptations for survival in a desert biome is
Animals in this biome tend to have scaly skin to save water and stay cool; plants have thick roots that capture water.
What is the desert biome?Deserts are extremely dry environments that support a diverse range of plants and animals. Deserts are classified into four types: hot and dry deserts, semi-arid deserts, coastal deserts, and cold deserts.Plants adaptationPlants in the desert are succulent, storing water in fleshy leaves, stems, or roots. Water absorption is well developed in the root system. The stem in these pants also performs photosynthesis. Their stems and leaves have a thick cuticle that protects them from excessive transpiration. To avoid excessive water loss, desert plants use the CAM pathway.Animals adaptationAnimals in the desert exhibit a variety of adaptations. Snakes, for example, come out in the open only at dawn or dusk. To avoid the heat, some small desert animals live in burrows.Camels, for example, store fat in their hump. This allows them to go a long time without food or water.Thus, we can conclude that Animals in this biome tend to have scaly skin to save water and stay cool; plants have thick roots that capture water. which is option C.
